What I am saying that if they hit back within 5 seconds, it's unlikely they've gotten any satisfaction from that page.
If they stay on the page for 2 minutes and then hit back, you'd figure they found something worthwhile before moving on to something else.
Google analytics cannot measure the time spent on site of a bouncing visitor. There is no end point to measure. So if there is only one page view the time spent on site is reported as 0:00.
I think some stats packages are able to measure page scrolling and other factors but still this is a measure that can't really be properly measured on a bouncing visitor.
So for a site with a 90% bounce rate the "time spent on site" relates to the 10% who don't bounce. Ie in your examples, the 90% bounce rate with 5 seconds spent on site means 90% bounce after spending an unknown amount of time on the site and the other 10% spend 50 seconds plus on the site.
For the 90% / 50 second example, again nothing is known on the 90% who bounce in terms of time on site and the other 10% spent 500 seconds+.
